LAMBDA-CYHALOTHRIN
Lambda-cyhalothrin is a synthetic pyrethroid insecticide used to control many types of insect pests. In pulses and soybeans, it’s label indicates control of cutworms, grasshoppers, lygus bugs, aphids and potato leafhopper. Lambda-cyhalothrin has been registered for use in Canada since 1996.
In 2021, Pest Management Regulatory Agency (PMRA) declared a re-evaluation decision of lambda-cyhalothrin, where several uses were cancelled due to human health concerns.
After thoroughly reviewing all relevant data, including the consideration of vulnerable populations (such as infants, seniors, children, and pregnant people), Health Canada has reinstated certain feed uses of the product.
These changes are designed to ensure that lambda-cyhalothrin continues to meet the requirements for protection of human health, based on the best available science.
